Functions

static NTSTATUS CreateNlsDirectorySecurity (_Out_ PSECURITY_DESCRIPTOR SecurityDescriptor, _In_ SIZE_T DescriptorSize)
 Creates a security descriptor for the NLS object directory.
 
GetNlsSectionName

Construct a name of NLS section.

Parameters
CodePageCode page number.
BaseInteger base used for converting to string. Usually set to 10.
UnknownAs the name suggests the meaning of this parameter is unknown. The native version of Kernel32 passes it as the third parameter to NlsConvertIntegerToString function, which is used for the actual conversion of the code page number.
BaseNameBase name of the section. (ex. "\\Nls\\NlsSectionCP")
ResultBuffer that will hold the constructed name.
ResultSizeSize of the buffer for the result.
Returns
TRUE if the buffer was large enough and was filled with the requested information, FALSE otherwise.

@implemented

BOOL WINAPI GetNlsSectionName (UINT CodePage, UINT Base, ULONG Unknown, LPSTR BaseName, LPSTR Result, ULONG ResultSize)
 
GetCPFileNameFromRegistry

Get file name of code page definition file.

Parameters
CodePageCode page number to get file name of.

◆ CreateNlsSecurityDescriptor()

NTSTATUS WINAPI CreateNlsSecurityDescriptor ( _Out_ PSECURITY_DESCRIPTOR  SecurityDescriptor,
_In_ SIZE_T  DescriptorSize,
_In_ ULONG  AccessMask 
)

Creates a security descriptor for each NLS section. Typically used by BASESRV to give Everyone (World SID) read access to the sections.

Parameters
[out]SecurityDescriptorA pointer to a correctly sized user-allocated buffer, that receives a security descriptor containing one ACL with one World SID. Its size should be at least equal to NLS_SECTION_SECURITY_DESCRIPTOR_SIZE.
[in]DescriptorSizeSize (in bytes) of the user-provided SecurityDescriptor buffer.
[in]AccessMaskAn access mask that grants Everyone an access specific to that mask.
Returns
STATUS_SUCCESS is returned if the function has successfully created a security descriptor for a NLS section name. Otherwise a NTSTATUS failure code is returned.
Remarks
This implementation has to be made compatible with NT <= 5.2 in order to inter-operate with BASESRV. In particular, the security descriptor is a user-provided buffer correctly sized. The caller is responsible to submit the exact size of the descriptor.
